Scanner will not track a
trunked system.
(continued)

The data frequency is
missing.

Find the data frequency
(see “Programming
Trunked Frequencies” on
Page 26).

PROBLEM

POSSIBLE CAUSE

REMEDY

The system you are try-
ing to track is a Type I
system, and the scanner
is set to scan Type II sys-
tems.

Set the scanner to
receive Type I trunked
frequencies. See “Scan-
ning Type I and Hybrid
Trunked Systems” on
Page 33.

Scanner will not stop
while scanning a scan
list.

No IDs have been
stored.

Store one or more IDs
(see “Scan Lists” on
Page 31).

The IDs you have stored
are not active.

Scan another transmis-
sion.

Scanner will not acquire
a data channel.

SQUELCH

is not cor-

rectly adjusted for trunk
tracking.

Adjust squelch for trunk
tracking. See “Setting
Squelch for the Trunk
Tracking Mode” on
Page 26.

The frequency used for
the data channel is miss-
ing.

Add the frequency used
for the data channel to
the frequency list. (see
“Programming Trunked
Frequencies” on
Page 26).

versations.

The system you are try-
